Is any hardware or software wallet which is safe to keep large amount of BTC safe and secure?

You can use electrum (https://electrum.org/#home). It's an open-source wallet. Of course, it's not that your fund is 100% safe if you use electrum.

If you want to keep a big amount of bitcoin completely secure, you should generate the private keys (or the seed phrase) using a secure tool and keep them always offline.
In the case of using a wallet like electrum, you should run that on an air-gapped computer (a device which has been always offline and will be never online) and your private keys (or the seed phrase) should never touch the internet.

No doubt it's a hardware wallet.  You can find it here, [BIG LIST] Hardware wallets (80+) (https://bitcointalk.org/index.php?topic=5282364.0).
Do you know why?  Because it leaves no footprints even in your device used, or even your computer infected with malware.

For a second choice which is free, that has been suggested above, Electrum is good as an alternative to hardware wallets.  All of these are good for storing Bitcoin for a long period of time or as cold storage.

Always remember the golden rule upon storing Bitcoin "Not your keys, Not your coin".

My always bet is a hardware wallet, nothing else. You can use electrum, already posted above, but you need to secure your device as well unlike hardware wallets that you can use them on unsecured environment, but ofc, you don't need to that just to test.

tl;dr if you have less than $500, go use Electrum[1] or BlueWallet[2]. on the other hand, if you have more than $500, grab a reputable hardware wallet from either Ledger[3] or Trezor[4].

Hardware wallet or not it doesn't matter, go with a fully open source wallet since thats the only way to be sure that your wallet is transparent, you need to keep your private keys in a safe location even if you using hardware wallet and that's why I said it doesn't matter which one you go with.

Open source wallet doesn't enough, it doesn't mean the code has been audited 100% and safe. You need to have a deep knowledge about program code in order to understand it, it will better to follow above expert opinions since they've experience and knowing the source of some non custodial wallet.

I have no idea why someone is really careless to protect their private keys, private keys isn't like your username that anyone know there's no problem, it's your password and you need to protect it as good as you can.

A hardware wallet will be a good place to keep a large amount of BTC because only you will determine when you want to use the wallet and only you will know where the wallet is hidden.
Right now, the hardware wallet price is not too expensive so you can buy one or two and send your BTC to two wallets and keep the passphrase safety in a place that only you will know.
Or you can use a HardDisk with installed Electrum and unplug any internet connection and do not connect it with another device that you do not know so you can make sure that your computer with the HardDisk is really safe.

You've got it wrong. If one's computer gets infected, no matter how clean and open source a wallet is, the funds will be stolen. And a hardware wallet can prevent that.
Also on hardware wallets you don't get private key to store, you get a HD seed (so you don't know what you're talking about and should not give advises before you learn more).
And the seed backup has to be kept offline in multiple (geographically distinct) safe places.

Both hardware and software wallets are only keeping keys for your coins, so more important thing would be to secure seed phrase backup or private key.
Software wallets are hot and connected to internet so they shouldn't be used for storing larger amounts of funds, for that purpose you can use cold storage.
Easy way for achieving this is with hardware wallets (open source is better option), or you can use separate air-gapped computer as offline storage.

As for me hardware wallet is good because it can store large amount of Bitcoin or coins and are  also secured.

Here are some good topic about security and privacy by Ratimov you can check it out.

Good topics on security and privacy

You can't go wrong with electrum wallet, mycelium, ledger nano x, open-source and full transparency, so make sure you keep your private key or recovery seed safe.

Then, if you've got a serious amount of Bitcoin, seeking a air gapped, completely offline solution would be beneficial. Something like a ColdCard, could do the trick. Although, pretty much any open source Bitcoin wallet is good enough for storing offline, as long as its stored securely. Obviously, hardware wallets allow users who might not understand the security risks, secure their Bitcoin to at least acceptable levels, right off the bat. ColdCard is a little more complex, and could potentially introduce errors if someone isn't entirely familiar with the process.

There's no problem if it's also a Ledger nano s.

Nano x is like the most recent version of the hardware wallet of Ledger but they're also selling an "S" version and it is what I've got. I guess others that have purchased long time ago got the s version and don't have any problems using it.

The price of two is quite far from each other and s is the cheaper version but you may want to have the features x has.

If you have a lot of bitcoins, you will find a safe way to keep your bitcoins safe. Enough to store any open source bitcoin wallet offline, unless it is securely stored. Open source bitcoin wallet is very safe for offline.

Coldcards are secure, but Coldcards use a variety of tactics to use their intelligence.
Hardware Wallet This is definitely a secure wallet. Those who keep Bitcoin safe here don't have to worry. And the problems that are at risk are the ones that they take seriously. They are only safe if they are fully informed about the process. I agree with your words. Hardware wallets they easily secure. But the cold card is a bit of a hassle because they keep it safe through tactics.

By now you should have gotten the right answer OP but I will like to warn you that either mobile, PC or hardware wallet make sure you keep your private key very safe, hardware wallet won't stop someone from importing your keys and stealing all your coins.

Others gave you some good wallets to choose. In crypto, you must practice decentralization for your capital. It is not only applied for investment but also for how you store your coin in wallets.

If you have Bitcoin, let's store your Bitcoin into different wallets. Don't store your coins in multiple addresses in one wallet because it does not make sense to protect your capital at all. If that wallet is compromised, all coins in all addresses inside will be stolen.

If you have your coins in multiple wallets, when one is compromised, others can still be safe.

Better, let's use multi-signature wallet that means to steal your coins, hackers will have to hack enough co-sign wallets. That sounds very impossible if you secure your wallets well enough.

First of all, I would like to tell you that you have heard and understood before. Then decide what to do in the cold head. Because a lot of money means it needs to be protected. When it comes to hardware wallets, make sure you keep your personal keys very secure, think hard about how to prevent someone from importing your hardware and stealing all your keys.

There are two types of cold card and hardware wallet. Coldcards are protected by their own intelligence and art techniques. The way the hardware wallet is protected is by the bat.

Am not sure there's any wallet with a maximum safety as you're expecting. Irrespective of the long history of such wallet, it must have had security issues at some point. For me, you just have your own role to play in the security of your coin, making sure your private keys are out of sight even to your manest man.

However, paper wallet could be recommended when looking for secure wallet, due to its offline character, but I won't advise newbie's in using it due to its complexity.

One can also use a HD wallet, generate a seed and use it basically like a paper wallet. Still, one has to do that on a completely safe environment and indeed, newbies may do mistakes with this (too).
On the other hand, one can easily generate a new seed with his hardware wallet and use that seed as a paper wallet. If the seed remains offline, backed up by hand writing, that's good.
But: does OP want to "bury his gold" onto a paper wallet or want to keep it at hand with a hardware wallet?

However, since the topic is about big amount of BTC, I think that hardware wallet is a must in the equation, no matter what he's doing afterwards (just never forget to store the backups safely)

Definitely a hardware wallet since the device itself can be kept inside a deposit box or in a lock where only you can have access to its funds using your private keys.

To be honest, I am somehow guilty of this because I mostly kept my BTCs inside our local exchange and external wallet. While this may be relatively secured, there is always that possibility where these exchanges may be the subject of hacks and scams, like what happened to Mt. Gox way back. In addition, several exchanges (including Binance) had experienced some hacking which resulted to loss of BTCs into the wallet of some.

Cold wallets, also known as hardware wallets, are generally a better option for saving crypto. They can’t be hacked and are like lockers.

It is wrong to call any wallet a "cold wallet" if that wallet connects to the internet at some point as is the case with the hardware wallets most used. Such devices have so far shown that they are relatively secure and are a much better choice than desktop, mobile or online wallets, but they also have some problems in the form of data leakage of their users, or vulnerabilities that can be exploited in a specific situation.

Vulnerabilities that have been found in the past and those that are likely to be found in the future are something that tells us that we should always be on the lookout for whatever crypto wallet we use.

I would choose hardware wallet like trezor or ledger if it is storing serious amount of Bitcoin but if it's not very big amount then i'd recommend using Electrum. Just make sure that the seed phrase or the 12 word recovery phrase are safely backed up either by handwriting or not. The wallet I am going to use is Electrum for receiving and sending small amount of Bitcoin or you can use bluewallet if you are not satisfied with Electrum. I have my wallet generated in Electrum a few years back and am still using it.

Whether it is a large amount or a small amount, it does not matter. But if you have stored coins, you can turn to help of a hardware wallet. These are secure wallets which help you keep your coins in secure form. It allows you to carry your coins around without worrying about them getting stolen by hackers, or your password gets compromised etc. But you should keep in mind that the biggest risk for losing coins comes from the user himself. So, you need to have a good password on your hardware wallet and keep your backup seed in a safe location. These are the two most common mistakes made by hardware wallet users.

Hardware wallet is always the best choice to keep large amount of btc. It is more secure because it needs a confirmation on the device before making a transaction. It's backup keys are also unique and not stored online making it more difficult for someone to hack it. Software wallets are not safe when your device is compromised. Hackers can easily access your wallet and stole all your assets anytime without your notice.

I believe this is one of the recommended ways to get good security if we want to store large amounts of bitcoin. Electrum allows users to create wallet without an internet connection, and it is a great security option for users.

Apart from that, there is an additional suggestion which is also a good option if they have a large number of bitcoin and it's like not hold all the bitcoin in one wallet ^{[meaning they have to create multiple wallets].} It will also help users to have extra security in case of losing access to the wallet or other things like hacking.

Many have already told . Even then I would also suggest for Electrum cold wallet so that you can secure your btc. It is known as one of the great wallet for holding btc . So Electrum hot wallet will be perfect for you

Electrum hot wallet or any other wallet of this type is not recommended for storing large amounts of Bitcoin, so your post contradicts yourself - cold wallet can be made with Electrum, which means that on one device that is always offline you have Electrum cold wallet, and on another device that is online you have a watch-only wallet that will be used for broadcast transactions that you will sign on an offline computer.

After you choose a wallet to use, you should have some wallets to store your Bitcoin.

Don't store all your Bitcoin in one wallet.

One of criteria to choose a wallet to use, does it support Segwit, Taproot?

Storing and using are different. You can choose one wallet to store large amount of BTC, and choose another wallet for payment process which will be used to store small amount of your BTC

[LIST] Wallets supporting Taproot (https://bitcointalk.org/index.php?topic=5371499.0)

This list is the best recommendable wallets to go after. Because a wallet is been selected base on different factors, that is, e.g usage, security and ability to convert crypto to fiat. So these listed wallets are good
